Specification of Letters Patent.

Patented July 22, 1913.

Application filed April 4, 1912. Serial No. 688,515.

To all whom it may concern:

Be it known that I, HENRY L. LEILroH, a citizen of the United States,and a resident of Delphos, in the county of Allen and State of Ohio,have invented a certain new and useful Lap-Joint for Corrugated Roofing;and I do hereby declare the following to be a full, clear, and exact.description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

My invention relates to sheet metal roofing of the corrugated type, andparticularly to the lap-joints for theroofing sheets.

' sheet, andhaving its outer leg .The object of my invention is toprovide a simple and improved lap-joint for corrugated roofing, which isinexpensive of formation, and adapted not only to effectually carry ofithe water or moisture which is present between the lapping edges byreason of condensation, capillary or siphonic action, butalso 'toprovide a.firm support for the lapping edges at the point of nailing thesame to the support or base member, thus preventing breaking down of thecorrugation during the nailing operation.

The invention is fully described in the following specification, and apreferred embodiment thereof is illustrated in the accompanyingdrawings, in which,

Figure 1 is a perspective view of a portion of a roof with my improvedroofing applied thereto, and Fig. 2 is an edge elevation thereof. 1

Referring to the drawings, lkdesignates the base or body of a roof ofthe usual board ing or other suitable construction, and 2 and -3 twoadjoining corrugated sheets havingthe overlapping and closely fittingedge cor? rugations 4 and 5 respectively.

Inthe carrying out of my invention I provide the corrugation 4 at itsouter edge 7 withthe integral trough 6, which trough has the inner leg 7adapted to rest at its lower end upon the roofing base 1 to hold theattached sheet corrugation firmly up under the overlapping corrugation 5on the other 8 extending upward to and also forming a rigid support forthe overlapping sheet corrugation, as' shown. The trough 6 is preferablydisposed slightly to one side of the center of the overlappingcorrugation 5 to enable the securing nails 9 for the sheets to be drivensubstantiallythrough the centers of the lapping corrugations in closeproximity to the inner trough leg 7, as shown. This enables the innertrough leg to prevent a battering'or hammering down of the corrugationsat the points of drivi of the nails therethrough, as would otherwise bethe case. The legs of the trough are preferably inclined slightlyoutwardly from a vertical plane to enable the corrugated sheets to bepiled one on top of another with their troughs fitting in nestedrelation one within another for shipping or storing. With this form ofsheet and integrally attached trough, the moisture or water which isdrawn between the lapping edges of the sheets by capillary or siphonicaction enters the associated trough 6 and is thereby carried to asuitable point of discharge.

I wish it understood that my invention is not limited to any. specificconstruction or arrangement of the parts except in so far as suchlimitations are specified in the claim.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent,-is,

In combination, a base, corrugated sheets mounted thereon having theiradjoining edge corrugations overlapped with the inner one terminating inan integrally formed trough having spaced vertically disposed sides ofunequal depth, the inner of said sides extending downwardly fromsubstantially the center of the associated sheet corrugation and restingon said base to provide a support for such corrugation and the tenter ofthe lapping corrugation, and the outer side forming a support for theouter lapping corrugation intermediate its center and loweredge, andsecuring members penetrating the lapped corrugations of the sheetsadjacent to the inner trough side and fastening 'to the base.

In testimony whereof I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.-

HENRY L. LEILICH.
